 DESCRIPTION OF THE EMBODIMENTS

FIG. 1 is a schematic of an electronic device located at a first position and fixed to a motherboard according to an embodiment of the invention. FIG. 2 is a side view of a heat dissipating assembly of an M.2 expansion card of the electronic device of FIG. 1. Referring to FIG. 1 and FIG. 2, an electronic device 10 of the present embodiment includes a motherboard 100 and a heat dissipating assembly of M.2 expansion card 200. The motherboard 100 includes an M.2 connector 120 and a single M.2 fixing hole 140. In addition, the M.2 connector 120 of the electronic device 10 may configure an M.2 expansion card 300. The heat dissipating assembly of M.2 expansion card 200 includes a heat dissipating body 220 and a locking member 240. The heat dissipating body 220 has a first end 222 and a second end 224 opposite to the first end 222. In addition, the heat dissipating body 220 further includes a fixed portion 222a located at the first end 222 and at least one screw hole 227.

It is worth mentioning that in the present embodiment, the heat dissipating assembly of M.2 expansion card 200 of the electronic device 10 applies for a plurality of M.2 expansion card 300 sizes. For example, the size of the M.2 expansion card 300 may be a sized of model 2230, 2242, 2260 or 2280, and the invention is not limited thereto.

As shown in FIG. 1, in the present embodiment, the locking member 240 of the heat dissipating assembly of M.2 expansion card 200 includes, for example, a screw. The at least one screw hole 227 on the heat dissipating body 220 includes a plurality of screw holes 227, and the number of the screw holes 227 is, for example, two. Further, a plurality of screw holes 227 are spaced apart on the heat dissipating body 220, and the arrangement locations of the plurality of screw holes 227 are on the midline extended from the first end 222 to the second end 224 along the heat dissipating body 220. The positions of the screw holes 227 correspond to various sizes of the M.2 expansion card 300 to detachably fix the M.2 expansion card 300 on the heat dissipating body 220 in conjunction with the locking member 240.

Furthermore, as may be seen from FIG. 2, when a screw (the locking member 240) is fixed on the screw hole 227, the stud portion of the screw (the locking member 240) may be abutted against the edge of the M.2 expansion card 300 opposite to another side of the M.2 connector 120 to ensure that the M.2 expansion card 300 is stably inserted into the M.2 connector 120 on the motherboard 100. In addition, the nut of the screw (the locking member 240) slightly holds the M.2 expansion card 300 such that the M.2 expansion card 300 more stably fits the heat dissipating body 220.

It should be noted that, in the present embodiment, the material of the heat dissipating assembly of M.2 expansion card 200 may be a material facilitating heat dissipation such as aluminum, carbonized alloy, or copper, but the invention is not limited thereto. In addition, as shown in FIG. 1, in order to facilitate the expression of the plurality of screw holes 227 on the heat dissipating body 220, in the drawings of the invention, the surface of the heat dissipating body 220 is shown as a plane, but is not limited thereto. Of course, in other embodiments, the heat dissipating body 220 may also be, for example, a fin or other shapes facilitating the heat dissipation of the heat dissipating assembly of M.2 expansion card 200.

FIG. 3 is a schematic of the electronic device of FIG. 1 disposed on a motherboard and located at a second position. FIG. 4 is a partially enlarged schematic of FIG. 3 from another viewing angle. Please refer to FIG. 3 and FIG. 4. In the present embodiment, the heat dissipating assembly of M.2 expansion card 200 is detachably disposed at a portion on the motherboard 100 adjacent to the M.2 connector 120. In addition, the heat dissipating body 220 further includes a tongue 224a located at the second end 224 of the heat dissipating body 220. The motherboard 100 also includes a tongue slot 160 located on the M.2 connector 120 and corresponding to the tongue 224a.

In detail, in the present embodiment, as shown in FIG. 4, the electronic device 10 further has a connector housing 150. The connector housing 150 is disposed over the M.2 connector 120 of the motherboard 100, and the tongue slot 160 is formed at the connector housing 150. Of course, in other embodiments, the connector housing 150 may be in other forms, and the connector housing 150 does not necessarily cover the M.2 connector 120 on the motherboard 100. The connector cover 150 only needs to provide placement for the tongue slot 160 and fix the tongue slot 160 and the M.2 connector 120 on the motherboard 100, and the invention is not limited thereto. In addition, when the heat dissipating assembly of M.2 expansion card 200 is disposed on the motherboard, the tongue 224a located at the second end 224 of the heat dissipating body 220 of the heat dissipating assembly of M.2 expansion card 200 is extended into the tongue slot 160 of the motherboard 100.

Further, the user detachably fixes the M.2 expansion card 300 to the heat dissipating body 220 through the locking member 240 of the heat dissipating assembly of M.2 expansion card 200. At this time, the user only needs to insert the tongue 224a of the heat dissipating body 220 into the tongue slot 160 of the motherboard 100 and simultaneously insert the M.2 expansion card 300 into the M.2 connector 120 of the motherboard 100. The heat dissipating assembly of M.2 expansion card 200 and the M.2 expansion card 300 are stacked and held at a second position P2 as shown in FIG. 3.

Next, please refer to all of FIG. 1 to FIG. 4. In the present embodiment, the locking member 240 of the heat dissipating assembly of M.2 expansion card 200 detachably fixes the M.2 expansion card 300 together with the heat dissipating body 220 and holds them at the second position P2. The user only needs to press the first end 222 of the heat dissipating body 220 of the heat dissipating assembly of M.2 expansion card 200, and the M.2 expansion card 300 may be moved together with the heat dissipating assembly of M.2 expansion card 200 from the second position P2 shown in FIG. 3 to the first position P1 shown in FIG. 1 to fit the motherboard 100. At this time, the heat dissipating assembly of M.2 expansion card 200 is fixed on the motherboard 100 through the fixed portion 222a of the heat dissipating body 220. It is worth mentioning that in the present embodiment, the sequence of operations described is merely an example. For example, the user may also first insert the M.2 expansion card 300 into the M.2 connector 120 of the motherboard 100 and then detachably fix the M.2 expansion card 300 to the heat dissipating body 220 through the locking member 240 of the heat dissipating assembly of M.2 expansion card 200. Of course, in other embodiments, the user may also have other installation sequences, and the invention is not limited thereto.

It should be noted that, in the present embodiment, for example, the fixed portion 222a of the heat dissipating body 220 may be a through-hole for a screw 20 to pass through the fixed portion 222a of the heat dissipating body 220 to fix the heat dissipating body 220 on the motherboard 100. In addition, since the distance between the heat dissipating body 220 of the heat dissipating assembly of M.2 expansion card 200 and the motherboard 100 has a certain height, in the present embodiment, a convex locking portion 30 is disposed on the motherboard 100. Therefore, the screw 20 may be stably locked to the convex locking portion 30 after passing through the fixed portion 222a of the heat dissipating body 220. Of course, in other embodiments, the fixed portion 222a may be, for example, a structure such as a snap, a latch, or the like, and is not limited thereto.

In addition, in the present embodiment, the tongue 224a of the heat dissipating assembly shown in FIG. 4 and the tongue slot 160 of the motherboard 100 are only examples, and in other embodiments not shown, as long as a detachable fixing method is used, the invention is not limited thereto. More specifically, in an embodiment not shown, the heat dissipating assembly of M.2 expansion card 200 may not even have the tongue 224a, and the motherboard 100 may not require the tongue slot 160. In other words, the user only needs to first fix the heat dissipating assembly of M.2 expansion card 200 and the M.2 expansion card 300 together by the locking member 240 and then insert the M.2 expansion card 300 to the M.2 connector 120 on the motherboard 100. As a result, the heat dissipating assembly of M.2 expansion card 200 and the M.2 expansion card 300 may still be held at the second position P2 shown in FIG. 3. Similarly, the user only needs to press the first end 222 of the heat dissipating body 220 of the heat dissipating assembly of M.2 expansion card 200, and the M.2 expansion card 300 may be moved together with the heat dissipating assembly of M.2 expansion card 200 from the second position P2 shown in FIG. 3 to the first position P1 shown in FIG. 1 to fit the motherboard 100. Then, the user only needs to fix the fixed portion 222a of the heat dissipating body 220 to the M.2 fixing hole 140 on the motherboard 100, and the M.2 expansion card 300 may be fixed on the motherboard 100 by the heat dissipating assembly of M.2 expansion card 200.

It should be mentioned here that, the following embodiments adopt the reference numerals of the embodiments above and a portion of the contents thereof, wherein the same numerals are used to represent the same or similar devices and descriptions of the same technical contents are omitted.

FIG. 5 is a side view of a heat dissipating assembly of an M.2 expansion card according to another embodiment of the invention. Please refer to FIG. 5. In the present embodiment, the locking member 240 of a heat dissipating assembly of M.2 expansion card 200a may be a stud (the locking member 240a) in addition to, for example, a screw. Further, when the user inserts the M.2 expansion card 300 on the M.2 connector 120 on the motherboard 100, the M.2 connector 120 itself has a partial effect of fixing the M.2 expansion card 300. Therefore, the user may also hold the M.2 expansion card 300 without a screw (the locking member 240). That is, the user only needs to fix the stud (the locking member 240a) without a nut on the screw hole 227 of the heat dissipating body 220 and lean the stud (the locking member 240a) against an edge of the M.2 expansion card 300 opposite to another side of the M.2 connector 120 to ensure that the M.2 expansion card 300 does not slip, and then the user may fix the M.2 expansion card 300 to the heat dissipating body 220.

FIG. 6 is a cross section of a heat dissipating assembly of an M.2 expansion card of an electronic device along an extending direction of a first end and a second end according to still another embodiment of the invention. Referring to FIG. 6, in the present embodiment, a heat dissipating body 220b further has at least one clamping arm 260. The clamping arm 260 is extended from at least one side of the heat dissipating body 220b, and the clamping arm 260 may detachably clamp the M.2 expansion card 300.

In detail, when the user inserts the M.2 expansion card 300 into the M.2 connector 120 on the motherboard 100 (FIG. 1), the user fixes the M.2 expansion card 300 to the heat dissipating body 220b using the locking member 240 (FIG. 1). At this time, the heat dissipating body 220b is located at one side of the M.2 expansion card 300, and the clamping arm 260 is hooked on another side of the M.2 expansion card 300. The clamping arm 260 of the further ensures that the M.2 expansion card 300 may be stably fixed with the heat dissipating body 220 without slipping. In the present embodiment, as shown in FIG. 6, the number of the at least one clamping arm 260 is, for example, two. Of course, in other embodiments, the invention is not limited thereto.

FIG. 7 is a schematic of an electronic device of still yet another embodiment of the invention. FIG. 8 is a partial schematic of a cross section of a heat dissipating assembly of an M.2 expansion card of the electronic device of FIG. 7 along an extending direction of a first end and a second end. Referring to FIG. 7 and FIG. 8 simultaneously, in the present embodiment, a heat dissipating body 220c of a heat dissipating assembly of M.2 expansion card 200c has a groove 226 extended from the position of the fixed portion 222a of the heat dissipating body 220c to a direction away from the first end 222 of the heat dissipating body 220c. The heat dissipating body 220c further includes a sliding member 228 slidably disposed in the groove 226. Moreover, the screw holes 227 of the heat dissipating body 220c are formed on the sliding member 228.

In detail, in the present embodiment, the screw hole on the sliding member 228 may be locked by the locking member 240. When the user needs to fix the M.2 expansion card 300 and the heat dissipating body 220c together by the locking member 240, the user may fix various sizes of the M.2 expansion card 300 using the characteristic that the sliding member 228 may slide freely in the groove 226.

That is, the user may fix various sizes of the M.2 expansion card 300 and the heat dissipating body 220c together in conjunction with the locking member 240 by sliding the sliding member 228 to the corresponding position. In this way, the manufacturer does not need to provide corresponding screw hole for each type of the M.2 expansion card 300 at the time of manufacture. Further, in the present embodiment, the issue that the heat dissipating assembly of M.2 expansion card 200c may not completely match various sizes of the M.2 expansion card 300 on the market due to the manufacturer not providing the screw hole corresponding to the M.2 expansion card 300 at the heat dissipating assembly of M.2 expansion card 200c does not occur. Further, the situation in which the sizes of the heat dissipating assembly of M.2 expansion card 200c and the M.2 expansion card 300 do not match and thus causing inconvenience to the user also does not occur.

FIG. 9 is a cross section of a heat dissipating assembly of an M.2 expansion card of an electronic device along an extending direction of a first end and a second end according to still yet another embodiment of the invention. Referring to FIG. 9, in the present embodiment, At least one clamping arm 260 is extended from at least one side of the heat dissipating body 220d, and the clamping arm 260 may detachably clamp the M.2 expansion card 300. Moreover, the heat dissipating body 220d has a groove 226. The heat dissipating body 220d further includes a sliding member 228 slidably disposed in the groove 226.

In short, the present embodiment combines the technical features of the above two embodiments while having the advantages of the technical features of the two embodiments. As a result, the user may more stably and conveniently fix the M.2 expansion card to the motherboard.

It should be noted that the related technical details of the present embodiment are similar to the embodiment of FIG. 6 and the embodiments of FIG. 7 and FIG. 8 and therefore are not repeated herein. It is worth mentioning that the locking member 240 shown in FIG. 6 to FIG. 9 is, for example, a screw. Of course, in an embodiment not shown, the locking member 240 may also be, for example, a stud (the locking member 240a), and the invention is not limited thereto.

Based on the above, the heat dissipating assembly of M.2 expansion card of the electronic device of the invention not only may provide heat dissipation function to the M.2 expansion card, the user may also fix the M.2 expansion card on the motherboard through the heat dissipating assembly of M.2 expansion card. In other words, the user may also first fix the M.2 expansion card and the heat dissipating body through the locking member and then fix the heat dissipating body and the M.2 expansion card together on the motherboard through the fixed portion located at the first end of the heat dissipating body and the M.2 fixing hole on the motherboard. In addition, the electronic device of the invention allows the manufacturer to simply provide a single M.2 fixing hole adjacent to each M.2 connector on the motherboard, and other M.2 fixing holes additionally provided adjacent to the M.2 connector in the prior art may be omitted.
